"Obvious" is always debatable... but here's my thoughts on this issue:
every object in the ZODB has an id attribute which can be 
accessed by its getId() method, and which is used to qualify which 
object within a folder (or other ObjectManager) you want, e.g.

http://my_zope_server:8080/foo/bar/getId 

...or in python...
context.foo.bar.getId()

... or just...
context.foo.bar.id

... either one yields the string "bar".

In python I'd say id might be ok to use as a variable name,
as long as you don't mind hiding that builtin (which would
be reason enough for me not to do it.)

As for dtml, <dtml-var id> already means something: 
it's equivalent to context.id in
a python script.  And your original question referred to DTML.
So I wouldn't ever define "id" in a dtml situation.
